I can't even remember what A-Team was about. Only the vague memories that I did watch it. And the music theme, which the trailer lacks IMHO.

It was 4 guys who were on the run from the army/police. Each week someone would hire them to undertake some sort of mission, which always ended up with them building some bizarre sort of machine or gun. It was a tad ridiculous, which was part of the charm. My favourite episode is still the one in which they convert a combine harvester into a machine which shoots cabbages. Then of course they use it to defeat a bunch of AK-47 wielding bad guys before legging it as the military police caught up with them.
